Laravel 验证器仅适用于失败

Question

我正在尝试在 laravel 中验证上传文件。

该文件只接受xlsx,xls and csv

我的控制器有这个工作代码

  public function project_import_excel(Request $request){
    $validator = Validator::make($request->all(), [
        'file' => 'required|max:5000|mimes:xlsx,xls,csv'
    ]);

    $modal = "active";

    if($validator->passes()){
        return redirect()
        ->back()
        ->with(['success'=>'File uploaded successfully!'])
        ->with('modal',$modal);
    }else{
        return redirect()
        ->back()
        ->with(['errors'=>$validator->errors()->all()])
        ->with('modal',$modal);
    }
}

我的blade 文件中有errors and success 的此会话

 @if(session('errors'))
   <div class="alert alert-danger" role="alert">  
        @foreach($errors as $error)
           <li>{{$error}}</li>
        @endforeach
    </div>
    <hr>

 @elseif(session('success'))

    <div class="alert alert-success" role="alert"> 
       {{ session('success') }}
    </div>
    <hr>

 @endif

如果我尝试上传.jpeg 或任何其他不是xlsx, xls, or csv 的文件

这会给我一个类似的消息

但是如果我上传一个像`

不想显示成功消息。我的if else 有什么问题吗？

问题是，它总是以session('errors')结束

更新 我试图删除这个mimes:xlsx,xls,csv 并且session('success') 工作正常。但是如何验证哪些文件是可接受的？

我的HTML 代码form

   <div class="modal fade" id="bulkProjMod" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
   <div class="modal-dialog" role="document">

Laravel validator and excel files error

这个答案，解决了我的问题！

   $validator = Validator::make(
    [
        'file'      => $request->file,
        'extension' => strtolower($request->file->getClientOriginalExtension()),
    ],
    [
        'file'          => 'required|max:5000',
        'extension'      => 'required|in:,csv,xlsx,xls',
    ]
    );

Answer 2

尝试以下方法：

@elseif(Session::has('success'))
<div class="alert alert-success" role="alert">
  {{ Session::get('success')}}
</div>
@endif

或

 @else(session('success'))

    <div class="alert alert-success" role="alert"> 
       {{ $success }}
    </div>
    <hr>

 @endif

Answer 3

试试这个

if ($validator->fails()) {
return redirect()->back()
    ->withErrors($validator)
    ->with([
        'modal' => $modal
    ]);
} else {
return redirect()->back()
    ->with([
        'success'=>'File uploaded successfully!'
        'modal' => $modal
    ]);
}

和

@if ($errors->any())
<div class="alert alert-danger" role="alert">  
    @foreach ($errors->all() as $error)
       <li>{{$error}}</li>
    @endforeach
</div>
<hr>
@else
<div class="alert alert-success" role="alert"> 
   {{ session('success') }}
</div>
<hr>
@endif

希望能成功

您可以尝试显示成功和错误消息以分隔条件：

if($validator->passes()){
    return redirect()
    ->back()
    ->with('success', 'File uploaded successfully!')
    ->with('modal',$modal);
}else{
    return redirect()
    ->back()
    ->with(['errors'=>$validator->errors()->all()])
    ->with('modal',$modal);
}

然后查看文件：

@if(Session::has('success'))
     <div class="alert alert-success" role="alert"> 
         {{ Session::get('success') }}
     </div>
@endif


@if(session('errors'))
    <div class="alert alert-danger" role="alert">  
       @foreach($errors as $error)
           <li>{{$error}}</li>
       @endforeach
    </div>
@endif
